<DIV><FONT face=Arial size=2>I have received several e-mails from some very
accomplished pilots who have indicated that they are perplexed regarding the
requirements regarding the proper execution of the snap maneuver. Specifically
what needs to be shown to the judge in order to score well. Even among the
judging community there is a lack of consensus with many misunderstandings of
what constitutes a "break" and recognizing the stalled condition and heaven
forbid, the auto-rotation.</FONT></DIV>
<DIV><FONT face=Arial size=2>It is apparent that a standard needs to be adopted
that will once and for all end the individualized interpretations being
submitted from all quarters (mine included).</FONT></DIV>
<DIV><FONT face=Arial size=2>If indeed there is a correct process involved to
bring about the proper execution of this maneuver, then it should be possible
for the people responsible for handing down the final definitives, to single out
the pilot who consistantly performs this maneuver to the precise satisfaction of
their judging criteria and have the performance video-taped and made part of the
NSRCA web-site and eliminate the confusion.</FONT></DIV>
<DIV><FONT face=Arial size=2>This will enable anyone to visit the web-site,
observe the process, and come away with the full knowledge of how to (as Robert
Gainey says) score TENS !</FONT></DIV>

Snap<BR>><BR>><BR>>> Bob, my personal experience tells me that
such a snap roll is only<BR>>> possible with little to no elevator,
and decent amounts of aileron and<BR>>> rudder. This shouldn't be a
great surprise to anyone who has thought<BR>>> about the control
inputs we prescribe to perform a snap. Elevator input<BR>>> causes the
plane to pitch, and pitch causes the plane to displace from<BR>>> its
former path, whether the wing is stalled or not. Rudder causes
the<BR>>> plane to yaw, but yaw is much less effective at causing the
plane to<BR>>> displace from its former path. Rudder during a roll
forces the tail and<BR>>> nose to rotate around the flight path. What
two things can a judge or<BR>>> pilot look for during a roll to
determine if it is a standard roll,<BR>>> barrell roll, or a snap
roll? The first is the tail being at an angle<BR>>> that isn't the
flight path and then not rotating around the flight<BR>>> path. The
second is the CofG staying on a rather straight
path.<BR>>><BR>>> A stalled wing (due to elevator application)
produces a ton of lift.<BR>>> That lift is going to drastically move
the CofG off the previous flight<BR>>> path. This is why I advocate
and practice very little elevator<BR>>> deflection during a snap.
Meeting the rules requires strong elevator<BR>>> application to begin
the snap, and it also _requires_ releasing most of<BR>>> that elevator
during the rotation.<BR>>><BR>>> Of course, this is all just
talk and typing. Most important is to<BR>>> ensure your snaps don't
tempt judges to whip out the big zero. And that<BR>>> you can hit
wings-level every time. Jeez, I better keep
practicing...<BR>>><BR>>> -Adam<BR>>><BR>>> Bob
